Energy efficient transformer

In a typical power distribution grid, electric transformer power loss typically contributes about 40-50% of the total transmission & distribution loss. Energy efficient transformers are therefore an important means to reduce T&D loss^[1]. With the improvement of electrical steel (silicon steel) properties, the losses of a transformer in 2010 can be half that of a similar transformer in the 1970s. With new magnetic materials, it is possible to achieve even higher efficiency. The amorphous metal transformer is a modern example^[2].
